PATENT OFFICE.

LUBRICANT-SUPPLYING DEVICE.

SPECIFICATION formingpart of Letters Patent No. 753,201, dated February 23, 1904..

Original application filed December 11, 1901, Serial No. 85,437. Divided and this application filed June 19, 1902. Renewed July 15,

. 1903. Serial No. 165,666. (No model.)

a citizen of the United States, residing at New 7 York, in the county of New York and State of New York, have invented certain new and useful Improvements in Lubricant-Supplying Devices, of which the following is a specification.

This invention relates to improvements in lubricant-supplying devices, and has special reference to a device for supplying a nonfluid oil to open bearings and journals such as are used in power plants, especially such as paper, textile, steel, lumber, bleachery, and dye plants.

The non-fluid oil heretofore mentioned is a heavy oil of about the consistency of cold petroleum jelly, which will not melt under 200 Fahrenheit.

This application is a divisional application of my application for patent upon lubricatingboxes filed December 11, 1901, Serial No. 85,437.

Another object of my invention is the production of a lubricant-supplying device which is adapted to hold and feed a lubricant, which lubricant is of acharacter that does not melt under 200 Fahrenheit and which -is always made of a material softer than the shaft, bearing, or journal upon which it is to operate, copper mesh or gauze being preferable.

It has been customary heretofore in applying solid lubricants to an open journal to use fibrous matter, such as cotton and woolen yarns or waste mixed with the lubricant, this method being very unsatisfactory, for the rea son that a great amount of the lubricant is thrown away when the waste is removed and a great amount of frictionis produced, and it has therefore been my intention to overcome these objections by dispensing with the above materials and using in their stead a materialsuch as metal or sheet-paper, wood, or similar Inaterial-which will conform to the shaft or journal and be perforated so as to allow the motion of the shaft to suck or draw the lubricant through the device and distribute the lubricant evenly upon the shaft.

To this end my invention consists of a supplying device embodying novel features of Referring to the drawings, A designates a shaft, which is provided with a box B, having inwardly-projecting flanges C for supporting my lubricant-supplying device D. This device consists of the frame having the long parallel sides E and the semicircular opposed end pieces or strips F, which form a binding and frame for the screen or gauze G. This screen or gauze is always made of a softer material than the shaft upon which it is usedas, for instance, on a steel shaft I employ a copper screen, said screen being substantially semicircular in cross-section, so as to rest upon and partly surround the shaft.

The vital point of my invention is the screen, which rests lightly upon the journal or bearing and which has been more particularly adapted for use with the non-fluid oil above mentioned, this device, being the only satisfactory device for supplying this particular lubricant or others of a similar nature.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A screen semicircular in cross-section, and a frame surrounding the edges of the screen having two parallel long sides and two end strips bent to a semicircle connecting the parallel sides.

2. A device for lubricating open journals, comprising a frame having two parallel sides and two ends bent to a semicircle, and a screen bounded by said frame and semicircular in cross-section.

In testimony whereof I aflix my signature in the presence of two witnesses.
